My invention relates to'tiltable windows and' more particularly to sashVWindows comprising vertically maintained lateral parts and a framehinged in these parts.

Hinged windows are known which can be turned down -into the roomfor-convenient cleaningafter the means interlocking the .frame and the'lateral parts have been released. It is, however, dangerous orundesirable if this release can beA effected by everybody, for example,by children or incompetent persons who may break the pane or may damagethe mechanism of the Window o r may fall out of the window bycarelessness. Objects of my invention are to make the interlocking andreleasing means fool-proof, to prevent these meansfrom being operatedinadvertently or by unauthorized persons, and to provide a stop for therelease which can be removed only by a key.

Also Windows are known which can be tilted intol an oblique positionadapted for ventilation. Such tilting does not involve the 'dangersmentioned before, and it is desirable that such tilting can be effectedby handy and always ready means without the necessity of using a key.Therefore, other objects are to provide means interlocking the frame andthe lateral parts in closed position of the window which means can bereadily released as far as to pemii; the frame to assume an obliqueposition, but whichV are-stopped from being released into a positionpermitting the frame to turn down completely.

Further objects are to provide means to secure a window in closed or inpartly opened position,`

to use the same means for these two purposes, to make these meansreleasable in two steps, to operate these steps by the same handy means,and to provide a removable stop preventing one of these steps.

Another object is to luse two separate lateral parts which are arrangedslidably in vertical direction for a window of this structure.

Still other objects are to achieve these results with simple,inexpensive, effective and reliable means and Withmeans that will notoperate accidently and that can be operated with a small force.

Still further objects and advantages will appear from the followingdescription of an exempliiying embodiment of my invention, from theappended claims and from the accompanying drawing in which:

Fig. 1 shows a vertical elevation of -a window embodying my invention,most parts being shown in a -cross-section taken along the line I-I -ofFig. 2 and seen from the lower side in Fig. 2, the 55 right side of thewindow being shown broken off; Fig. 2 shows a horizontal crosssecti0n ofthe same embodiment, taken along the line 2-2 in Fig. l and seen fromthe upper side.

Fig. 3 shows a vertical side view of the same embodiment seen from theleft side in Figs. 1 and 2, the left lateral part being shown in acrosssection taken along the line {im-3 in Fig. 2, the frame beingshown'in an oblique position, a completely turned down position ofthe'frame being indicated-by dotted lines.-

Fig. 4 shows a vertical cross-section of the upper ledge of the window,taken along the line 44 in Fig. 2 and represented -on a larger scale.

yReferring to the drawing., numeral 5 -indicates the lateral parts, and6 the frame or easement of the window. The-parts 5 may be connected to abuilding in an openingthereof in any known and suitable manner, forexample, stationarily or slidably inserted between vertical rails '1.`The frame 6 is hinged to the parts 5 preferably by two horizontal pivots8'positioned near the lower edge of the frame. A glass 4pane 9 isinserted in the frame 6 in conventional manner. A lever arm l0 is hingedto the lateral part 5 by a horizontal pivot IIy and is positionedbetween'this lateral part and the frame so that the'arm Ill canturn in aplane perpendicular tothe plane of the pane 9. Preferably, anotheridentical lever arm IIJ is similarly positioned at the symmetricallyopposite sidel of the window. `The arms I0 have open-` ings adapted to-be engaged -by bolts as will be described later. These openings may beformed, for example,by slots I2.. l f f The upper part or ledge of theframe 5 is hollow and may be formed by an upper horizontal -wall I3, alower horizontal wallI4, an inner vertical wall I5 and an outer verticalwall I6. In the space surrounded by these walls, bodies II arepositioned slidably in a direction parallel tothese walls. Preferably,one body I'I is arranged at each of the two ends of this space. Thebodies I'l may have slotsV I8 through which bolts I9 and 20 afxed to thewalls I3 and llv pass.l A bolt 2| is aixedto the outer end -of each bodyIl and projects therefrom in a lateral, horizontal direction. Theinnerend ofeach body I1 has a recess 22 -in the bottom of which two steps areformed, one of these `steps formed bysa surface 23 and-the other step bya surface 24 having a larger distance from the outer end of the body IIthan the surface A23.

The ,bodies `II are permanently drawn to the l The bodies can bewithdrawn to the inner sides against the action of the springs 25,preferably by exible means acting simultaneously on both bodies. Forexample, a cord or chain 27 is afxed to each body II, and these twochords are passed through openings 26 in the wall I4 and have endshanging down and forming an united string 29 which can be easily pulledby a person standing on the oor of the room.

Stops areprovidedfor -the inward movement of the bodies I1 andmay beformed by' a member 30 having two arms eXtending into the recesses 22.tion, as shown in Figs. 1 and 2, thesearms are spaced from the bottomsof these recesses; The

member 30 is so movable or adjustable that itcan act as a stop bycontact with either the surfaces 23 or 24. This adjustment may bemade,`for eX- ample, by a turning movement of the membergSIlV which maybe provided with pivots 3I passing through bores in the walls I3 and I4.v v

Preferably,y the adjustment' of the member 33 is made by means `of aspecial key fitting a key hole 3Ia in the wall I 5 and, after passingthis key hole, engaging a recess 32 in the member 301whereby the key 33turning in a vertical plane turns the member 30 suilioiently in ahorizontal plane. When'the window is closed, the bolts 2| pass throughthe slots I2 of the lever arms I0 and also engage holes 34 providedco-axially in the lateral parts `5 as shown in Figs. l and2. Y,In thisposition of the window, the arms I are positioned vertically and contactstops 35 aixed to the lateral parts -5. Ordinarily the member-3D remainspermanently in the position shown in the same iigures. l l

When a person pulls the string 29,` the bodies I1 slide inwardly untilthe surfaces 24 contact the member '30 and, at the same time, the bolts-2I leave the holes 34 and thereby releasethe frame `6 which, eventuallyby a slight further pull on the string 29, will fall down into theoblique position shown in Fig. 3 in full lines. In this position, thebolts 2I contact the lower ends of the slots I2, and the arms Illpreventfurther downfall of the frame 6, This position of the window is adaptedfor ventilation. The ventilation may be improved in 'conventional mannerby a second window arranged below vor above the rst window andpreferably constructed and operated in the saine manner whereby thesetwo obliquely posi# tioned windows facilitate a circulating ventilation.

When the frame 6 is lifted again into'its vertical position, the bolts2I automatically engage the holes 34 and secure the frame in itsoriginal position. 1 l

In order to open the window completelyor to bring it into a positionconvenient lfor cleaning, the key 33 is passed throughthe hole 3 la intothe recess 32 and then turned until the arms of the member 36 are inline with the surfaces 23. This can be done whether the window is closedas in Fig, 1 or partly open as in Fig; 3. When thereafter a person pullsthe string 29, the bolts 2| move to the inner sidev suriciently far asto leave theslots YI2 of the lever arms lIll whereby the frame 6 isfullyreleasedla'n'd can be turned down into the position shown inFig. 3 indotted lines.

n Atthe same time, the lever arms I!) return into or remain in thevertical position shown in Fig.

3 in dotted lines. s

The frame 6 may be supported in the lowered Vposition and may beprevented from falling fur- 'ther down by suitable means, for example byarms 36 and 31. The arm 36 is rotatable around a When the bodies I'I arein their outer posi;A

pivot 38 afXed to the lateral part 5. The arm 3l is rotatable around apivot 39 aixed to the frame 6. The ends of these two arms opposite tothese pivots are connected with each other by a pivot 4i). When thewindow is closed the arms 36 and 31 are folded into parallel position.Similar arms 36 and 31 may be provided at the other side of the frame.

In order to secure the window again in closed position, it .is .onlynecessary to raise the `frame 6 until the window is shut, L`pulling, thestring 2S. Then, upon release of the string, the bolts 2I reg turnautomatically into the original interlocking position. Then, the key 33may be used to turn `themember 30 into its original position.

I'desire it understood that my invention is not Y Vconiined to theparticular embodiment shown and described, the same being merelyillustrative, and thatmy invention may be carried out in other 530 wayswithout departing from the spirit of my invention as it is obvious'thatthe embodiment shown` and described is only one of the many that may-'beemployed to attain 'the objects of my invention. i v
